Abstracts

Water is one of the most essential natural resources . A good assessment of both surface and groundwater always leads to an effective and sustainable water resources management. In Vietnam, the management of water resources has mainly focused on surface water, however, the problems related to groundwater have not been managed properly. This study aims to assess surface and groundwater availability in Dong Nai river basin by integrating SWAT and MODFLOW models. These models run individually and integrated through the recharge rates. The simulation results were then compared and showed good agreement with observed data. The results showed Tuyen Lam, Da Huoai and Dak Song districts are the locations which have high surface water availability, in the range of 40 50 l/s/km2. The groundwater simulation indicated the areas having high groundwater availability are located at the same places with the regions having high surface water. Dak Song is the region having the highest groundwater availability with around 9 l/s/km2.
